Abstract: Extrusion processability of non-fluorinated melt-processable polymers is improved by introducing a process aid package comprising at least two unimodal fluoroelastomers having different Mooney viscosities.

Abstract: Extrusion processability of non-fluorinated melt-processable polymers is improved by introducing a fluoropolymer process aid by means whereby the weight average particle size of the fluoropolymer is greater than 2 microns as it reaches the extruder die entrance.

Abstract: Ethylene vinyl acetate (EVA)/ethylene-styrene interpolymer (ESI) blends are described that are useful in preparing foams which exhibit improved compression set resistance, dimensional stability and rebound resilience at similar foam densities than known foam systems, e.g. EVA. The cross-linked foams of this invention are particularly useful in fabricating footwear and gasket products.

Abstract: The present invention is a rigid thermoplastic polyurethane (RTPU) comprising units of butane diol (BDO) and a polyethylene glycol (PEG) of the type HO--(CH.sub.2 CH.sub.2 O).sub.n --H, where n is an integer from 2 to 6. The RTPU of the present invention addresses a problem in the art by providing a potentially lower-cost alternative to an RTPU prepared from hexane diol, and further providing an RTPU that can be customized to a desired toughness, T.sub.g, yield strength, and transparency. The RTPUs that are prepared from certain mole ratios of BDO and the PEG exhibit a surprisingly high degree of toughness manifested by increased tensile elongation to break.

Abstract: The present invention is a rigid thermoplastic polyurethane having a T.sub.g of at least 50.degree. C. having a sufficient concentration of units derived from an aromatic diol to lower the temperature at which the rigid thermoplastic polyurethane can be melt processed. The present invention is also a thermoplastic polyurethane with a flex modulus of at least 100,000 psi, and having a sufficient concentration of units derived from an aromatic diol to lower the temperature at which the thermoplastic polyurethane can be melt processed. The compositions of the present invention show improved processability with insubstantial loss of physical properties.
